SpringSecurity+jwt+redis基于數(shù)據(jù)庫(kù)登錄認(rèn)證的實(shí)現(xiàn)

 更新時(shí)間：2023年09月25日 10:29:36   作者：笑的像個(gè)child  
本文主要介紹了SpringSecurity+jwt+redis基于數(shù)據(jù)庫(kù)登錄認(rèn)證的實(shí)現(xiàn),其中也涉及到自定義的過(guò)濾器和處理器,具有一定的參考價(jià)值,感興趣的可以了解一下

前言

本項(xiàng)目主要是一個(gè)SpringSecurity+jwt+redis基于數(shù)據(jù)庫(kù)登錄認(rèn)證的Demo，其中也涉及到自定義的過(guò)濾器和處理器，希望能對(duì)大家有幫助，本文中所有代碼正常情況下可以直接復(fù)制使用。

一、前期準(zhǔn)備

1. 創(chuàng)建項(xiàng)目

在這里插入圖片描述

勾選需要用到的框架

在這里插入圖片描述

2. 引入相關(guān)依賴

提示：有三個(gè)依賴需要手動(dòng)添加，其余的在創(chuàng)建項(xiàng)目時(shí)就生成了

3. 創(chuàng)建數(shù)據(jù)庫(kù)并生成數(shù)據(jù)

數(shù)據(jù)庫(kù)名為javasec，可自行更改

role

4. 整體項(xiàng)目結(jié)構(gòu)

可以按照我的來(lái)，也可自行決定

在這里插入圖片描述

二、具體實(shí)現(xiàn)

1. 編寫(xiě)配置文件

提示:修改數(shù)據(jù)庫(kù)的密碼，以及redis的端口號(hào)，我使用的7000，redis的默認(rèn)端口號(hào)為6379

server:
  port: 8080
spring:
  datasource:
    url: jdbc:mysql://localhost:3306/javasec?characterEncoding=utf8&useSSL=false&serverTimezone=Asia/Shanghai&rewriteBatchedStatements=true&allowPublicKeyRetrieval=true&allowMultiQueries=true
    password: ****
    username: root
    driver-class-name: com.mysql.cj.jdbc.Driver
  ## redis配置
  redis:
    database: 0 # 數(shù)據(jù)庫(kù)索引 默認(rèn)為0
    host: 127.0.0.1    # redis服務(wù)器地址
    port: 7000    # 端口號(hào)
    password:    # 密碼（默認(rèn)為空）
    timeout: 5000 # 連接超時(shí)時(shí)間（毫秒）
    jedis:
      pool: # 連接池配置
        max-active: 8 # 連接池最大連接數(shù)（使用負(fù)值表示沒(méi)有限制）
        max-wait: -1 # 連接池最大阻塞等待時(shí)間（使用負(fù)值表示沒(méi)有限制）
        max-idle: 8 # 連接池中的最大空閑連接
        min-idle: 0 # 連接池中的最小空閑連接
mybatis:
  mapper-locations: classpath:mapper/*.xml
  type-aliases-package: com.javasec.bean

2. 創(chuàng)建實(shí)體類(lèi)

package com.javasec.bean;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.experimental.Accessors;
/**
 * @Author YZK
 * @Date 2023/7/5
 */
@Data
@Accessors(chain = true)
@AllArgsConstructor
@NoArgsConstructor
public class Role {
    /**
     * 數(shù)據(jù)庫(kù)主鍵
     */
    private String id;
    /**
     * 角色uid
     */
    private String rid;
    /**
     * 角色名稱(chēng)
     */
    private String name;
    /**
     * 角色名稱(chēng)中文
     */
    private String nameZh;
}

創(chuàng)建的User需要實(shí)現(xiàn)UserDetails接口

package com.javasec.bean;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.experimental.Accessors;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import java.util.ArrayList;
import java.util.Collection;
import java.util.Date;
import java.util.List;
/**
 * @Author YZK
 * @Date 2023/7/1
 */
@Data
@Accessors(chain = true)
@AllArgsConstructor
@NoArgsConstructor
public class User implements UserDetails {
    /**
     * 數(shù)據(jù)庫(kù)主鍵
     */
    private String id;
    /**
     * 用戶uid
     */
    private String uid;
    /**
     * 用戶登錄名
     */
    private String username;
    /**
     * 用戶登錄密碼
     */
    private String password;
    /**
     * 用戶創(chuàng)建時(shí)間
     */
    private Date time;
    /**
     * 用戶是否被鎖
     */
    private boolean locked;
    /**
     * 用戶是否開(kāi)啟
     */
    private boolean enabled;
    /**
     * 賬戶登錄token
     */
    private String token;
    /**
     * 用戶角色列表
     */
    List<Role> roles;
    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        List<SimpleGrantedAuthority> authorities = new ArrayList<>();
        for (Role role : roles) {
            authorities.add(new SimpleGrantedAuthority(role.getName()));
        }
        return authorities;
    }
    @Override
    public boolean isAccountNonExpired() {
        return true;
    }
    @Override
    public boolean isAccountNonLocked() {
        return !locked;
    }
    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }
    @Override
    public boolean isEnabled() {
        return enabled;
    }
}

3. 編寫(xiě)dao層代碼以及mapper

UserDao中主要是通過(guò)username來(lái)查詢數(shù)據(jù)庫(kù)中是否存在這個(gè)用戶

RoleDao主要是用來(lái)查詢登錄用戶的角色列表（一個(gè)用戶可能有多個(gè)角色）

package com.javasec.dao;
import com.javasec.bean.User;
import org.apache.ibatis.annotations.Param;
/**
 * @Author YZK
 * @Date 2023/7/5
 */
public interface UserDao {
    User loadUserByUsername(@Param("username") String username);
}
package com.javasec.dao;
import com.javasec.bean.Role;
import org.apache.ibatis.annotations.Param;
import java.util.List;
/**
 * @Author YZK
 * @Date 2023/7/5
 */
public interface RoleDao {
    List<Role> getUserRoleByUid(@Param("uid") String uid);
}
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.javasec.dao.UserDao">
    <resultMap type="com.javasec.bean.User" id="UserMap">
        <result property="id" column="id" jdbcType="VARCHAR"/>
        <result property="uid" column="uid" jdbcType="VARCHAR"/>
        <result property="username" column="username" jdbcType="VARCHAR"/>
        <result property="password" column="password" jdbcType="VARCHAR"/>
        <result property="time" column="time" jdbcType="TIMESTAMP"/>
        <result property="locked" column="locked" jdbcType="INTEGER"/>
        <result property="enabled" column="enabled" jdbcType="INTEGER"/>
    </resultMap>
    <select id="loadUserByUsername" resultMap="UserMap">
        select *
        from user
        where username = #{username}
    </select>
</mapper>
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.javasec.dao.RoleDao">
    <resultMap type="com.javasec.bean.Role" id="RoleMap">
        <result property="id" column="id" jdbcType="VARCHAR"/>
        <result property="rid" column="rid" jdbcType="VARCHAR"/>
        <result property="name" column="name" jdbcType="VARCHAR"/>
        <result property="nameZh" column="nameZh" jdbcType="VARCHAR"/>
    </resultMap>
    <select id="getUserRoleByUid" resultMap="RoleMap">
        select *
        from role r,
             user_role ur
        where r.rid = ur.rid
          and ur.uid = #{uid}
    </select>
</mapper>

4. 編寫(xiě)springSecurity相關(guān)處理器

編寫(xiě)UserServices

進(jìn)行身份驗(yàn)證之前，Spring Security會(huì)調(diào)用loadUserByUsername()方法來(lái)獲取用戶信息。該方法通常用于在數(shù)據(jù)庫(kù)中查詢用戶信息，然后將其封裝在UserDetails接口的實(shí)現(xiàn)類(lèi)中，并返回給Spring Security。

package com.javasec.sec;
import com.javasec.bean.User;
import com.javasec.dao.RoleDao;
import com.javasec.dao.UserDao;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
import javax.annotation.Resource;
import java.util.Objects;
/**
 * @Author YZK
 * @Date 2023/7/5
 */
@Service
public class UserServices implements UserDetailsService {
    @Resource
    UserDao userDao;
    @Resource
    RoleDao roleDao;
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = userDao.loadUserByUsername(username);
        if (Objects.isNull(user)) {
            throw new UsernameNotFoundException("用戶不存在");
        }
        user.setRoles(roleDao.getUserRoleByUid(user.getUid()));
        return user;
    }
}

登錄處理器

這個(gè)處理器中有兩個(gè)方法，onAuthenticationSuccess()方法主要用于登錄成功時(shí)為header設(shè)置token，并將整個(gè)已經(jīng)登錄的對(duì)象(authentication)存入到redis中，onAuthenticationFailure()方法主要用于登錄失敗時(shí)返回提示信息。

package com.javasec.sec.handler;
import com.alibaba.fastjson.JSONObject;
import com.javasec.bean.User;
import com.javasec.utils.JwtUtil;
import com.javasec.utils.RedisUtils;
import com.javasec.utils.result.SystemResult;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import org.springframework.security.web.authentication.AuthenticationSuccessHandler;
import org.springframework.stereotype.Component;
import javax.annotation.Resource;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
/**
 * @Author YZK
 * @Date 2023/7/15
 */
@Component
public class CustomAuthenticationHandler implements AuthenticationSuccessHandler, AuthenticationFailureHandler {
    @Resource
    RedisUtils redisUtils;
    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
        User user = (User) authentication.getPrincipal();
        String jwt = JwtUtil.generateToken(user);
        if (redisUtils.exists("login:" + user.getUid())) {
            redisUtils.remove("login:" + user.getUid());
        }
        response.setCharacterEncoding("utf-8");
        response.setContentType("text/html; charset=UTF-8");
        redisUtils.set("login:" + user.getUid(), jwt);
        response.setHeader("token", jwt);
        response.getWriter().write(JSONObject.toJSONString(SystemResult.success("登錄成功")));
    }
    @Override
    public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {
        response.setCharacterEncoding("utf-8");
        response.getWriter().write(JSONObject.toJSONString(SystemResult.fail(401, exception.getMessage())));
    }
}

Jwt過(guò)濾器

該過(guò)濾器可以攔截每一次請(qǐng)求，并驗(yàn)證header中是否存在token，驗(yàn)證成功則會(huì)通過(guò)UsernamePasswordAuthenticationToken傳給一個(gè)authentication provider驗(yàn)證成功則會(huì)返回一個(gè)帶有授權(quán)信息的身份驗(yàn)證對(duì)象。如果身份驗(yàn)證失敗，則應(yīng)返回一個(gè)未通過(guò)的身份驗(yàn)證對(duì)象。

package com.javasec.sec.filter;
import com.alibaba.fastjson.JSON;

import com.javasec.utils.JwtUtil;

    @Resource
    RedisUtils redisUtils;
    public JwtAuthenticationFilter() {
    }
    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
        // 從請(qǐng)求頭或請(qǐng)求參數(shù)中獲取JWT token
        String token = request.getHeader("token");
        try {
            Claims claimByToken = JwtUtil.getClaimByToken(token);
            assert claimByToken != null;
            String tem = JSON.toJSONString(claimByToken.get("user"));
            User user = JSON.parseObject(tem, User.class);
            UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(
                    redisUtils.get("login" + user.getUid()), null, user.getAuthorities());
            SecurityContextHolder.getContext().setAuthentication(authenticationToken);
        } catch (Exception e) {
            // 驗(yàn)證失敗，可以進(jìn)行一些處理
            response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
            log.error(e.getMessage());
        }
        filterChain.doFilter(request, response);
    }
}

5. 本文所用的工具類(lèi)

        //開(kāi)啟過(guò)濾器，并將其置于UsernamePasswordAuthenticationFilter過(guò)濾器之前
        http.addFilterBefore(jwtAuthenticationFilter, UsernamePasswordAuthenticationFilter.class);
    }
}

三、測(cè)試

1. 測(cè)試類(lèi)

有兩個(gè)賬戶，一個(gè)是root,一個(gè)是user,密碼都是123456

先寫(xiě)一個(gè)測(cè)試類(lèi)，這個(gè)類(lèi)中的接口需要有相關(guān)權(quán)限的用戶才能訪問(wèn)

package com.javasec.controller;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
/**
 * @Author YZK
 * @Date 2023/8/21
 */
@RestController
public class TestController {
    //該接口需要admin權(quán)限才能訪問(wèn)
    @PreAuthorize("hasAuthority('admin')")
    @GetMapping("/test1")
    public String test() {
        return "測(cè)試";
    }
    //該接口需要user權(quán)限才能訪問(wèn)
    @PreAuthorize("hasAuthority('user')")
    @GetMapping("/test2")
    public String demo() {
        return "這是demo接口";
    }
}

2. 使用root賬戶登錄

在這里插入圖片描述

訪問(wèn)test1接口，沒(méi)有問(wèn)題

在這里插入圖片描述

訪問(wèn)test2接口，被禁止，權(quán)限錯(cuò)誤的信息也可以自定義，本項(xiàng)目未自定義

在這里插入圖片描述

3. 使用user賬戶登錄

同樣的登錄成功的信息

在這里插入圖片描述

訪問(wèn)test1接口，被禁止

在這里插入圖片描述

訪問(wèn)test2接口，訪問(wèn)成功

在這里插入圖片描述

redis中登錄成功存儲(chǔ)的jwt，有兩個(gè)賬號(hào)登錄，所以有兩條

在這里插入圖片描述

總結(jié)

后端生成的jwt應(yīng)該存儲(chǔ)在redis中，每次處理請(qǐng)求時(shí)都應(yīng)檢驗(yàn)一次用戶的權(quán)限信息，以及jwt是否過(guò)期，在前后端分離的項(xiàng)目中，前端登錄后，后端生成的jwt會(huì)在請(qǐng)求頭中設(shè)置，然后前端拿到后，會(huì)存儲(chǔ)在localstorage中(只是舉例，想存哪兒隨意)，在前端發(fā)起請(qǐng)求時(shí)，也會(huì)攜帶著token到后端進(jìn)行檢驗(yàn)。

到此這篇關(guān)于SpringSecurity+jwt+redis基于數(shù)據(jù)庫(kù)登錄認(rèn)證的實(shí)現(xiàn)的文章就介紹到這了,更多相關(guān)SpringSecurity+jwt+redis登錄認(rèn)證內(nèi)容請(qǐng)搜索腳本之家以前的文章或繼續(xù)瀏覽下面的相關(guān)文章希望大家以后多多支持腳本之家！
